Martin's Stump Killer
Martin's Stump Killer
Martin's Stump Killer, manufactured by CSI, is a effective water-soluble herbicide that manages and eliminates undesired trees and new tree growth in forest and non-crop sites.
As a 2-in-one product, Martin's Stump Killer includes a blue dye that allows the applicator to readily view and mark the area during application. Once a cut surface has been treated the product will continue to control the growth for up to 2 years.
Martin's Stump Killer is a ready to use herbicide to such an extent applications easily seep into the cut surfaces of tree stumps to provide complete plant growth control.
Tools Needed
Apply Martin's Stump Killer with a handheld pump sprayer or disposable paint brush. You will need to cut the tree down to a stump prior to application with either a chainsaw or axe.
If used as tree injection, then you will need to use a tree injector such as a Hypohatchet injector or similar device.
Do not apply through any type of irrigation equipment.
How to Use
- Step 1: Cut down the tree to a small stump and branches until they are stubs. Determine how much Martin's Stump Killer to use by calculating the size of the treatment site. To find this, measure the length and width of the treatment area in feet and multiply (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 = acre). The application rate for tree injections is to apply 1 millimeter of undiluted Martin's Stump Killer solution through the bark completely around the tree trunk at 2 to 3 inch intervals between the edges of the injector wounds. Make injections 2 to 4 feet above the ground. For stump treatments with paintbrush or spray application equipment use 4 gallons of product per acre.
- Step 2: Adjust the spray nozzle to a low pressure spray. Spray until cut surface of tree stump and stubs is wet, but not to the point of run-off. Avoid applications within the root zone of desirable trees. Thoroughly wet the cambium area next to the bark.
- Step 3: Do not apply more than 4 gallons of Martin's Stump Killer per acre per two years. Do not make more than one application every two years. On right-of-way and other non-crop areas do not apply more than 4 gallons of product per acre per year. Do not make more than one application per year.
Where to Use
Use Martin's Stump Killer on cut trees and branches in forests and non-cropland areas such as fencerows, roadsides, right-of-way, and other similar sites.
Do not apply on residential or commercial lawns or near ornamental trees and shrubs
When to Use
Martin's Stump Killer can be used at any point of the season as long as ground is not frozen or covered by snow. Maple tree species should not be treated during the spring sap flow.
